I am trying to get my door gaps correct before I repaint, and I am having a heck of a time getting the gap on the bottom of the door to look good. If I match the top of the door with the pillar/door jamb and get the correct door jamb gap, then I end up with a wider gap all the way across the bottom of the door. Is this supposed to be a wider gap? This is all original metal, so nothing has been modified. I am using a paint stick for setting my door gaps. Maybe this is too narrow?
